Subject: [PATCH] kcsan: clean up redundant empty macro arguments in atomic ops.

---------------------------------------------------------

- Removed unnecessary trailing commas from DEFINE_TSAN_ATOMIC_RMW() macro
  calls within DEFINE_TSAN_ATOMIC_OPS() in kernel/kcsan/core.c

- It passes checkpatch.pl with no errors or warnings and
  introduces no functional changes.
